Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 628279-07-2 CS-T-23932 N-[4-[1-(2-Fluorobenzyl)-3-butyl-2,6-dixo-2,3,6,7-tetrahydro-1H-purin-8-ylmethyl]phenyl]acetamide.

628279-07-2 CS-T-23932 N-[4-[1-(2-Fluorobenzyl)-3-butyl-2,6-dixo-2,3,6,7-tetrahydro-1H-purin-8-ylmethyl]phenyl]acetamide (CAS 628279-07-2) is a high-purity analytical reference standard with the molecular formula C25H26FN5O3 and a molecular weight of 463.50 g/mol.

Structurally, 628279-07-2 CS-T-23932 N-[4-[1-(2-Fluorobenzyl)-3-butyl-2,6-dixo-2,3,6,7-tetrahydro-1H-purin-8-ylmethyl]phenyl]acetamide (C25H26FN5O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 463.50 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
